Hi, This is a topic to discuss on the bf-cycles mailing list. We use a different pixel filtering method which fits better on the GPU. If you set the filter width to 10 then yes, you might be wasting half the samples. But for a typical filter width the number of wasted samples would be quite small in my opinion. Still it would be good to improve this, but I'm not sure where the half the samples number comes from.
